Recovering from social interactions

I really love communication and interaction with people, but from time to time I need to be alone with myself, because I feel like I'm becoming less sincere and losing myself, and I'm just tired. At such moments, I can be too silent and calm, which makes me uncomfortable in front of close people, but understanding that I need this now in order to return to a socially active state later helps me cope with the feeling of shame in front of others (I'm a little worried that it looks like a loss of interest in communication) Do you go through similar periods? What helps you to go through them less stressfully and as efficiently as possible?
